Furnace Types and Efficiency

Furnace Types and Efficiency

tipsSo, we have been looking at the different factors to consider when choosing your next heating and cooling solution in your home in St Louis near Creve Coeur MO.  The fact is, there are several things to be considered before settling in on one that you think will work best.  Efficiency is a definite topic of interest and to look at this well, when searching for your St Louis Heating install near Creve Coeur, you will want to examine the different types of stages, so we will describe them in the following write up.

Single-stage is indicative of older furnaces that often have motors with only one speed setting and that is high. These motors run at maximum capacity no matter how much or little heating you need. Because maintaining a stable indoor temperature rarely requires the furnace to work at full blast, a lot of energy goes to waste in this type of a set-up.  Unfortunately, people often settle for this style heating in St Louis near Creve Coeur because the initial cost is lower.

Then, we have a two stage motor option which is one where the motor can run on a high and a low speed setting. Because the low setting is usually enough to keep your temperature stable, this motor can save you energy by most often running at a slower speed. It kicks into high only when your heating demand is great enough to require a large amount of warm air quickly in order to reach the desired temperature in your home.  Your St Louis Heating Sales near Creve Coeur recommends this style over the single stage heating.

Modulating or variable-speed is the third type furnace to discuss.  A variable-speed motor isn’t restricted to specific settings, but it can run at any speed within a set range. This allows it to choose the precise speed that’s most efficient for the given heating demand. According to sources online, “You’ll enjoy optimal energy efficiency along with a more stable and even temperature.”

Cooling Efficiency and SEER

Cooling Efficiency and SEER

acWe covered choices to be made when looking at heating options in St Louis near University City MO.  We are now in the space to move along to cooling and all that it means to be involved in finding the most efficient and adequate system for you home in St Louis MO.  As we discuss cooling service in St Louis MO, it is also important to keep cool with the right air conditioner in the heating and cooling realm in St Louis near Ladue MO.  “Finding an efficient, high-performance cooling system is a critical part of choosing a new HVAC system in our area. To find an air conditioner like this, it helps to know the basics of how this equipment works.”  Just like the time we took to discuss heating solutions on behalf of your St Louis Heating Sales near Ladue, we will spend extra time covering the air conditioners in the cooling department.

The following was found during our research on behalf of your St Louis Cooling Repair near University City MO and is pertinent in our discussion, “Air conditioners cool using a fluid called refrigerant, which circulates through the system. As the refrigerant passes through the indoor evaporator coil, it absorbs heat from the air and also removes moisture. The cool, dehumidified air is blown into the ducts. The hot refrigerant moves to the outdoor condenser coil to get rid of the heat it picked up.”

Air conditioner efficiency is listed and known to us by the seasonal energy efficiency ratio (SEER). This number tells you how much energy the system uses relative to the amount of heat it can remove when busily cooling your space. A higher SEER means greater energy efficiency. Even if your air conditioner is only 10 years old, upgrading to a recently manufactured model with a higher SEER could reduce your cooling bills by 20 to 40 percent.  We will discuss the ins and outs of more than the SEER and all that relates to cooling choices in the next two posts on behalf of your St Louis Cooling Sales near University City MO.

 

Finding Your Next Heating Solution

Finding Your Next Heating Solution

guideHeating sales and service in St Louis near Collinsville IL is here to look up close at the decision process of finding your own furnace.  There are several factors to consider in the heating and cooling realm when looking at the HVAC options.  “The efficiency of fuel-burning furnaces is rated by the annual fuel utilization efficiency (AFUE), which indicates how much of the fuel burned goes toward providing heat compared to how much is lost in the exhaust fumes. The higher the AFUE, the more efficient the furnace.”  Obviously, fuel efficiency is one of the most important aspects of consideration when looking for the best furnace solutions for your home of office.

Some older furnaces still in use have AFUEs as low as 56 percent, while today’s most efficient models reach efficiencies as high as 98.5 percent. The previous fact should serve as an example in terms of which range you will encounter in your St Louis Heating search.  Much of this change is due to improvements in air handler efficiencies over the years and will also be responsible for the range of efficiencies from one St Louis Heating Service to the next.  There are also three known basic types of air handlers to investigate when choosing a new HVAC system for your home or office.

The following is what we learned when researching the subject on behalf of your St Louis Heating Sales and Service near Collinsville IL:  There are three different stages, all of which will be described in details in the post to follow on behalf of your Heating Sales in St Louis near Collinsville IL.  There are three, single-stage, stage-two and modulating or variable speed.  Each of these three will be discussed in greater detail in the next post.

Hydronic Heating

Hydronic Heating

hydronicLooking for the best means of heating and cooling your home in St Louis near St Charles MO brings us to a discussion regarding your health as it pertains to air quality. Using hydroponic heat can avoid certain health risks.  “Even short-term exposure to dust, allergens, and other contaminants can irritate existing cardiovascular and respiratory illnesses. They can make it more difficult to breathe, putting more stress on your heart and lungs.”

There are greater risks associated with long term exposure to these contaminants that can damage cells and prematurely age the lungs. People who are healthy may develop respiratory conditions like asthma, emphysema, or bronchitis when air quality is poor. The pollutants that are blowing around your home can even put you at risk for some types of cancer, so you can see why you may want to take the time to research more closely just what you use in your heating and cooling environment at home.

When it comes to air quality in your HVAC, your St Louis Heating and cooling sales near St Charles, MO has found to pay special consideration to children, seniors, and people of any age who already have respiratory or cardiovascular disease and/or a weakened immune system.  According to our heating and cooling research, these are at the greatest risk of illness due to poor air quality in the home. This risk is completely eliminated with a hydronic system. According to your St Louis Heating Sales near St Charles MO, the “Hydronic heating doesn’t blow allergens and contaminants around your house or give them a place to hide in the ductwork.”  Just remember this, there is really no trade-off between healthier air and a more comfortable living space. It would be great to consider the differences found in our St Louis heating and cooling research and decide for yourself on which method of heating delivery works best for you.

Popping and Rattling in Your Cooling System

Popping and Rattling in Your Cooling System

noisesMy cooling system is still making noises that I don’t understand.  Should I be worried?  We have been on the topic of heating and cooling noises made by your HVAC system in St Louis MO near Afton for some time now.  And, we know that some are harmful and legitimately concerning while others can be dismissed.  “Popping sounds when you turn your system on and off you can breathe a sigh of relief.” The popping sound is due to your metal ductwork expanding and isn’t a problem whatsoever, according to your St Louis heating and cooling repair near Afton MO.  “For elimination of the sound, insulation such as foam or rubber can help limit the noise.”

There exist other sounds emitted by your Cooling system in St Louis that can be of greater concern, such as the thumping and clacking we discussed in a previous post.  When you hear such things, be sure to call your heating and cooling installation specialists near Afton for a complete HVAC work up.  Other sounds will be covered in posts to follow on behalf of your St Louis cooling installation and repair.  For now, let’s move onto rattling.  Rattling sounds usually indicate loose debris blowing around within your heating and cooling system in St Louis near Afton.  This, as harmless as it may seem, can be a big problem if left unchecked.  “Even something as small as a loose screw rattling about could lead to significant issues down the line. If the debris is larger in size, the rattling noise may sound more like a scraping noise, which is also not to be ignored.”

There is a level of DIY here, if you can pinpoint the location of the rattling, unscrew the vent and see if you can remove the debris. If not, contact a professional to locate and extract the debris as soon as possible, so as to protect your heating and cooling system in St Louis from potential permanent damage.

Natural Refrigerants

Natural Refrigerants

naturalNatural refrigerants are an unexplored subject in the cooling world. According to our recent research on behalf of your St Louis Cooling sales near O’Fallon, we have many reasons to further explore their impact on the environment and energy efficiency, as well as ozone damage, etc, based on compressor choices and options available in the cooling industry.

“While natural refrigerants are already a reality in commercial refrigeration, the home appliance industry has lagged behind in adoption.”  We have already explored oil free compressors, now the natural ones are up next for discussion. The United States has lagged behind Asia, Europe and Latin America in providing consumers with natural refrigerant options, according to our research on behalf of your St Louis Cooling Sales and Service near O’Fallon MO. “This is starting to change as end users, particularly in states with strict energy regulations and high levels of environmental awareness, are starting to demand natural refrigeration solutions.”

How does the EPA play a role here in the United States? “There is also increasing pressure from the Environmental Protection Agency (EPA) and the Department of Energy (DOE) on manufacturers to find refrigeration solutions that do not depend on fluorinated gases (F-gases).” Another encountered source, The Association of Home Appliance Manufacturers (AHAM), recently published an open letter announcing intentions to phase out the R134a refrigerant by 2024 while the EPA announced that a ban on this refrigerant could happen as early as 2021. R290 will be the natural refrigerant used in cooling with many compressors in St Louis MO near O’Fallon and it has zero ozone depletion potential so has much gain.

Oil Free Compressors Advantage

Oil Free Compressors Advantage

advantageThere exist a variety of subjects with cooling at the center.  Besides HVAC, Refrigeration is the next biggest related category and within that, we have much to research and discuss regarding compressors, more specifically still, the efficiency and ability of one compressor to the next in the St Louis Cooling Sales and Service near St Peters MO.  Oil free compressors are today’s focus.

Labeled as a breakthrough technology, oil free compressors are truly capable of revolutionizing residential refrigeration for the household market. According to facts gathered on behalf of your St Louis Cooling Repair near St Peters, “This technology, which has been available for households since 2014, expands the possibilities of appliance and kitchen design. Because it does not use oil, it is smaller and provides the manufacturer with more freedom in terms of where within the unit the compressor is installed.” This flexibility is a big factor in cooling since it not only provides appliance designers flexibility in how the equipment is configured but can also help save valuable real estate in the home kitchen where things already tend to be tight for many.

Cooing experts report that the home sector’s first oil-free compressor uses no oil due to a special surface coating and a single bearing lubricated by the refrigerant gas itself. Running on a wider range of capacity modulations instead of switching on and off, it is able to result in minimum temperature variation and better food preservation, according to all we read on behalf of your St Louis Cooling Sales near St Peters MO.  Described by professionals in the industry as compact, flexible, quiet, energy efficient and over 90% recyclable, the oil-free compressor is poised to transform home refrigeration without a doubt.

Alternate Cooling Dynamics

Alternate Cooling Dynamics

alternativeDid you know that when it comes to cooling a space, there exist many different means to an end?  “Dais Analytics in Florida, in partnership with Oak Ridge National Laboratory (ORNL), is developing a new membrane-based rooftop air conditioner, which would use water as a refrigerant instead of conventional chemicals.”  We are always seeking, according to the research recently done on behalf of your St Louis Cooling Sales near O’Fallon, ways in which to function sans chemicals. Not only is this technology perfect for sweltering, humid summer nights, but it could also save 30%-50% in electrical consumption compared to today’s roof top units, not to mention work to cut out the chemicals that we are always doing our best to avoid.

“United Technologies Research Center in Connecticut is exploring electrocaloric, solid-state technology to develop a heat pump that will keep a space cool without using any chemical refrigerants. This technology is ideal for residential and small commercial buildings.” It’s small and quiet, and could result in 25% system efficiency improvement, along with possessing fewer mechanical parts.  It is much improved in the Cooling Maintenance in St Louis near O’Fallon with the likelihood of increased reliability that results in a total reduction of your chances of losing A/C in the midst of a heat wave!

One of the other goals in this movement and wave of technology is based, according to our research done on behalf of your St Louis Cooling Sales and Service near O’Fallon is to develop an energy storage system that integrates with HVAC units to reduce the overall energy requirements of A/C systems by utilizing waste-heat that would otherwise be lost in traditional systems. Integrating ground-level diverse energy storage with HVAC could reach overall energy storage efficiency of 70% and improve HVAC performance by 35%.

Green Alternative Heating

Green Alternative Heating

greenWe spent the previous post discussing the measures that one randomly selected University was taking in the way of energy efficiency with green technology.  “Green heating and cooling systems fall under two distinct categories: passive and active.” Passive systems work by maximizing nature’s ability to heat and cool without furnaces or air conditioners [source: Green Technology]. “Among other things, passive technology includes constructing homes with white or light-colored roofs that reflect the sun’s energy instead of absorbing it.” As a result, the amount of energy it takes to cool a house is less. Passive designs also use windows that can keep the heat out and cool air in.  They remind me of staying safe from a sunburn by sitting in the shade as opposed to the chemical (active ways) of sunscreen.

According to our recent research on behalf of your St Louis Heating and Cooling near O’Fallon MO, active designs use a variety of mechanical heating and cooling systems. These systems tend to run on solar power, geothermal power or other sources of green energy.  It’s a gradual one, but the increase in green-energy use, according to your St. Louis Heating Sales near O’Fallon MO, in recent years is slowly having an impact.

“For one thing, Americans saved more than $19 billion in 2008 by using various green heating and cooling systems [source: U.S. Department of Energy].”  The cost is high, though, according to your St Louis Heating installation near O’Fallon. “But these green systems are not cheap — some solar collectors cost between $30 and $80 per square foot for installation.”  There are incentive programs offered now and then by the government, but not consistent enough to really go into details here.  The next several posts will cover all of the other green heating and cooling methods we uncovered.

Passive Cooling

Passive Cooling

passiveOn behalf of your St Louis Cooling Repair near South County MO, we are on a regular search for new information and research to pass along to you, in regards to green energy and cost effective, environmentally friendly ways to handle the heating and cooling of your home or business.

Along those lines, did you know that the sun is the ultimate provider of green energy?  A couple things that make it so are the constant and renewable nature of Solar power, the fact that it is not about to run out anytime soon.  There are, according to our research on behalf of your St Louis Cooling Installation near South County, ways in which you can benefit and enjoy the power of solar energy without the effects of direct sunlight.  “Passive solar energy is simple, has little to no moving parts and requires minimal upkeep. Passive solar-energy systems are designed to use natural principals of heat transfer instead of machines such as furnaces and air conditioners [source: Passive Solar Resources].”

It turns out, according to all that we read for your St Louis Cooling Sales and Service near South County, passive solar technology uses the building’s walls, windows and floors to collect, store and release the sun’s energy. “However, passive solar homes still need mechanical equipment, such as a forced-air system or radiant flooring to keep the temperatures cool in the summer and warm in the winter [source: Arizona Solar Center].” Direct gain systems are supposed to be the easiest of them all in terms of installation of cooling capable solar panels in St Louis MO.  In such systems, sunlight passes through windows where the light is converted into thermal energy. The walls and floors directly absorb and store the heat energy. As long as the room temperature is high, the interior of the homes will hold on to the heat. “When the temperature drops at night, the stored heat radiates through the living space.”
